Arsenic exposure in postnatal life impacts the growth of children, but little is known about the effect of in-utero arsenic exposure on growth very early in childhood. The aim of this study was to examine the associations between in-utero arsenic exposure and the growth of infants from birth to 6 months of age using monthly follow-up data. A prospective cohort study was conducted in rural areas of Bangladesh with 108 mother-infant pairs. This study identified a negative association between in-utero arsenic exposure and head circumference of infants 1-6 months of age (coefficient = -1.20, 95% confidence interval [CI]: -1.97, -0.42), and the effect was more pronounced in the earlier ages of 1-3 months (coefficient = -0.88, 95%
-1.70, -0.05). Because head circumference is considered as a surrogate of brain size, our findings suggest that in-utero arsenic exposure influences brain growth during an important developmental period.

This study aimed to find an indicator at three months to predict overweight and short stature at two years in small for gestational age (SGA) infants. A total of 468 SGA infants and 4642 appropriate f...
Mechanistic studies support the potential for mercury (Hg) to alter immunity, including via in utero exposure. As yet, there are few prospective studies of in utero Hg exposure and subsequent immune-r...
Arsenic, cadmium and lead are toxic environmental contaminants. They were shown to be associated with telomere length (TL) in adults. Although they can cross the placental barrier, the effect of prena...
Arsenic is widely distributed in the environment in both inorganic and organic forms. Evidence from animal studies suggests that maternal inorganic arsenic may lead to the development of orofacial cle...
One in ten infants born in the United States is born preterm, or prior to 37 weeks gestation. Exposure to elevated levels of metals, such as lead and arsenic, has been linked to higher risk of prete...
While reducing arsenic (As) exposure in Bangladesh and the U.S. must continue to be a top priority, this has proven difficult. After decades of mitigation efforts, 42 million people in Ban...
The opioid neonatal abstinence syndrome (NAS) is a condition of withdrawal symptoms after utero exposure to opioids. Sublingual buprenorphine shows promise as a new treatment in NAS. This...
The American Academy of Pediatrics has recommended that growth in size (weight, length, and head circumference) and in body composition (fat and lean mass) in preterm infants should adhere...
Iron is essential for brain development and there is a well established association between iron deficiency in infants and poor neurological development. In Sweden, about 5% of newborns ha...
This study evaluates auditory neural maturation by auditory brainstem evoked response in late preterm and term infants with in utero iron deficiency compared with neonates with normal in u...
Disorders associated with acute or chronic exposure to compounds containing ARSENIC (ARSENICALS) which may be fatal. Acute oral ingestion is associated with gastrointestinal symptoms and an encephalopathy which may manifest as SEIZURES, mental status changes, and COMA. Chronic exposure is associated with mucosal irritation, desquamating rash, myalgias, peripheral neuropathy, and white transverse (Mees) lines in the fingernails.

A condition occurring in FETUS or NEWBORN due to in utero ETHANOL exposure when mother consumed alcohol during PREGNANCY. It is characterized by a cluster of irreversible BIRTH DEFECTS including abnormalities in physical, mental, and behavior development (such as FETAL GROWTH RETARDATION; MENTAL RETARDATION; ATTENTION DEFICIT AND DISRUPTIVE BEHAVIOR DISORDERS) with varied degree of severity in an individual.
The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.
The consequences of exposing the FETUS in utero to certain factors, such as NUTRITION PHYSIOLOGICAL PHENOMENA; PHYSIOLOGICAL STRESS; DRUGS; RADIATION; and other physical or chemical factors. These consequences are observed later in the offspring after BIRTH.
An infant having a birth weight of 2500 gm. (5.5 lb.) or less but INFANT, VERY LOW BIRTH WEIGHT is available for infants having a birth weight of 1500 grams (3.3 lb.) or less.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
